AIR QUALITY IN TERMS OF PARTICULATE MATTER (PM10) AND ELEMENT COMPONENTS IN ANTANANARIVO CITY

摘要

The main objective of this research was to study the size distribution of the toxic elements, undesirables ones and PM10 in the aerosols of Antananarivo urban areas using Total Reflection X-ray Fluorescence. This work was carried out in the framework of a Co-ordinated Research Program organized by the IAEA in 1998. The results of the study show that lead exceeds the recommended value of the WHO (0.5μg.m~9-3)) and the PM10 particles exceed also the recommended value (150μg.m~(-3)). Therefore, the Antananarivo urban area is classified as saturated zone for both parameters (lead and paniculate matter).
